【摘要】 在中国最大的贝类批发市场———金贝广场的暂养净化项目研发过程中,对贝类进行了暂养密度、循环水量、曝气形式、水温与耗氧量、充氧能力、循环水质、停电时限等试验研究。结果表明:贝类的暂养密度不宜超过0.3 kg/L,曝气充氧形式宜以池外曝气为主,暂养水温以6℃为宜,水中溶解氧大于3.7 mg/L时,对贝类活度的影响不大,换水次数不宜少于3次/d,停电时间不宜超过3 h。更多还原

【Abstract】 The paper introduces the researching results of shellfish aquaculture and purification in Jinbei Square.Several tests has been done such as aquaculture density,circulating water volume,aerating pattern,water temperature and oxygen consumption,oxygenation capacity,circulating water quality,death of halting electricity etc.The results indicate that it is suitable for the aquaculture density to be less than 0.3 kg/L,aerating oxygenation patterns to be aerating outside the tanks,aquaculture temperature to be 6℃,shellfish’s activity to be normal when dissolved oxygen is over 3.7 mg/L,the circulating frequency to be more than 3 per day,and halting electricity to be less than 3 h.更多还原
